Growth against the P/E multiple. Up and to the right is cheaper and faster — the quality-growth idea in one picture. Points beyond the axis are pinned to the edge and marked off-scale rather than allowed to compress everything else.

Winner per row is the stronger grade; where grades tie, the better figure breaks it. A true tie or a missing value shows no highlight.

Insurance - Property & Casualty · $266.49 · beta 0.53
Why now
Insurance - Property & Casualty · market cap $13.1b. 12% off the 52-week high of $303.94. 6 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $326.67 (implying +23% upside).
Moat
ROE 18% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately. Financial moat — scale of deposit base / underwriting franchise plus regulatory capital advantages. The largest players compound book value through cycles that erase smaller competitors.
Risk
Regulatory capital risk — stricter capital requirements (CCAR, Basel) can force a dividend cut or a capital raise; the largest banks are most exposed because they're held to the tightest standards.

Insurance - Property & Casualty · $2,060.63 · beta 0.28
Why now
Insurance - Property & Casualty · market cap $4.9b. 12% off the 52-week high of $2333.00. Revenue growing +23%, comfortably above the S&P median. PEG 0.81 — paying under fair value for the growth rate.
Moat
Net margin 38% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 20% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately. Financial moat — scale of deposit base / underwriting franchise plus regulatory capital advantages. The largest players compound book value through cycles that erase smaller competitors.
Risk
Balance-sheet financial — book value, net interest margin, and credit loss provisions are the lever points; a rates regime change or a deterioration in the loan book moves the stock more than EPS does.

Common questions

Is WTM or AIZ the better stock?

WTM scores higher: WTM 80.0, AIZ 74.0 out of 100 on the Bull Rankings quality-growth score, which blends business quality, growth and valuation into one number. A higher score means a stronger business at a more reasonable price — it is not a price target or a recommendation.

How are WTM and AIZ scored?

Each carries the same 0–100 quality-growth score used everywhere on the site, built from three pillars — quality (profitability and returns on capital), growth (revenue and earnings), and value (what you pay for them) — combined as a geometric mean, so a weak pillar cannot be papered over by a strong one.
